4
Q

how do ACE inhibitors work

A

they inhibit angiotensin converting enzyme from synthesizing angiotensin 2, a potent vasoconsrictor. angiotensin 2 also causes aldosterone to be secreted. which is an antidiuretic. increasess blood volume and pressure

Q

how do beta blockers work

A

they reduce heart rate by blocking beta receptors in the heart. they also reduce renin secretion, thus aldoseterone II and angiotensin
decrease blood pressure

Q

what are the characteristics of vasospastic angina

A

caused by intense coronary arterial spasms
pain may come at rest
smoking, hyperinsulinemia, and insulin resistance are factors

25
what type of drugs are used for long term management of angina
beta blockers and calcium channel blockers
26
what type of drugs are used for acute angina management
nitroglycerines
27
what is a mild diuretic
thiazide
28
what is a powerful diuretic
forosimide (lacic)
29
what should be instructed of patients taking diuretics
increase electrolytes, especially potassium
30
what are potassium sparing diuretics
spirolactone and aldolactone
31
what shouldn't be done with potassium sparing diuretics
you shouldn't increase potassium (can lead to hyperkalemia)
32
when should diuretics be taken
in the morning (don't wake up to pee)
33
what is the drug of choice for ventricular dysrhythmias
lidocaine,xylicaine
34
why is a beta blocker a bad idea for a women with a slow heart beat
because they slow down the heart rate
35
what is a dysrhymia
any deviation from the normal rhythm of the heart
36
what causes dysrhythmias
ischemia/MI toxicants drugs hypokalemia
37
what is the normal level of digoxin
.5-2 ng/dl
38
what are the effects of digoxin
positive ionotrope negative chromotrope negative dronotrope
39
what are the side effects of digoxin overdose
``` nausea diarrhea vomiting seeing halos hypokalemia ```
40
what happens with digoxin and a diuretic
hyperkalemia
41
what things shouldn't someone on warfarin/coumadin do
anything that can cause bleeding | shaving, flossing
42
what tests are used to test the effects of warfarin
prothrombin time and INR | PT-INR
43
what are the signs and symptoms of serious side effects of warfarin
``` bleeding skin rashes fever nausea diarrhea dermatitis alopecia urticaria abdominal cramps anorexia ```
44
what pain killer should be taken with warfain/coumadin
tylenol/acetometaphen
45
what is the antidote for warfarin/coumadin
vitamin K
46
what is the mechanism of action for anticoagulants
prevent clot formation, don't break down current clots
47
why would LMWH be administered
because it has a more predictable anticoagulant response it doesn't require prolonged aPTT it doesn't require prolonged lab tests
48
what is LMWH
low molecular weight heparin
49
what is the lab test used to monitor heparin effects
aPTT activated partial thromboplastin time
50
what is the first choice antiplatelet drug
aspirin, because it is the least powerful
51
why do we use clopdogrel
its a powerful antiplatelet that we use so we don't have to use an anticoagulant
52
at what point do we call a doctor if on antihypertensive drugs and we are in hypotension
if systolic is less than 90
53
what must we caution our patient about antihypertensive drugs,
they need to watch for orthostatic hypotension
54
what is primary hypertension
idopathic, cause unknown
55
what is secondary hypertension
hypertension due to a secondary cause, it goes away once the other problem is fixed
56
concerning pulse, when should we call the doctor
if its less than 60 or more than 100
57
when taking calcium channel blockers what tests do we check to observe renal function
BUN and creatinine
58
what is verapamil
calcium channel blocker
59
ways to reduce cholesterol
diet | exercise
60
what is the first line drug of choice for hypercholesterolemia
statins
61
what are ideal LDL values
less than 100 (190 is very high)
